Can the type size of Scrivenings titles be changed?

I like this feature. In the Editor, I use size 18 type. The Scrivenings titles seem much larger, and, in fact, they are. They have a font size of 28.

It makes a bit of sense to have them a different size so that it’s easier to differentiate between the titles and the actual text. I would not want them to have the same size.

But 28 is huge. I tried changing one of them to 16 point just as an experiment, but it immediately reverted to 28.

Is there a way to set the size Scrivenings titles?

Windows version :

This setting, if changed, should stick to the new font/font size.
